About Converting Cubic inch per Weeks to Gallon per Seconds
Cubic inch per Weeks and Gallon per Seconds both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per seconds = cubic inch per weeks × 7.157745e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per weeks equals 2.709501e-11 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic inch per weeks-to-gallon per seconds factor of 7.157745e-9.
Simple example
1 in3/wk × 7.157745e-9 = 7.157745e-9 gal/s
1 cubic inch per weeks = 7.157745e-9 gallon per seconds.
Real-world example
60 in3/wk × 7.157745e-9 = 4.294647e-7 gal/s
60 cubic inch per weeks = 4.294647e-7 gallon per seconds.

What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic inch per weeks to gallon per seconds conversion exact?
Yes. Both cubic inch per weeks and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 7.157745e-9 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
